Unspecified injury of left kidney, subsequent encounter

This code signifies an unspecified injury to the left kidney that is being treated or evaluated after the initial encounter. The nature of the kidney damage is not specified, meaning the exact type of injury (e.g., contusion, laceration, rupture) is not documented or known. It indicates ongoing care for a previously sustained left kidney injury.

This code is appropriate for follow-up visits, subsequent hospitalizations, or rehabilitation encounters where a patient is receiving care for an uncharacterized injury to their left kidney. It should be used when the initial injury has already been diagnosed and treated, and the patient is returning for further management, monitoring, or recovery.

• Ensure the documentation clearly indicates a "subsequent encounter" for the injury.
• Only use this code when the specific type of left kidney injury is not documented.
• Always sequence this code after any definitive treatment codes or other relevant primary diagnoses.
